Hair cutter



Dec. 8, 1953 F. D. lNFANTlNO HAIR CUTTER Filed Nov. 5, 1952 INVENTORFRANCESCO D. INFANTINO BY ATTORNEY Patented Dec. 8, 1953 UNITED PTENTQFFICE 4 Claims.

My invention relates to a new and useful hair cutter of the type used bya person to cut or trim his own or to enable one not especially skilledin the artof hair cutting to trim or out another persons hair.

An object of the invention is to produce an exceedingly simple,effective and durable device of the character mentioned in which asafety razor blade is removably mounted in an adjustable slidetravelling in tracks artially contained within a control box or bodyconstantly open at the bot tom and also provided with an open upper endnormally closed by a lid supporting the adjustable slide or razor bladecontainer and the means for adjusting said slide, the cutting edge ofthe razor blade being enclosed within a wire guard having the individualelements secured to the control box, said guard being of triangularconfiguration to provide opposed slanting sides as guides to restagainst a persons head during the hair cutting operations.

Another object of the invention is to produce a hair cutter in whichboth sides of the structure are identical and without lateralprotuberances, other than the elements of the guard, 1,5;

whereby the device can be used on either the right or left hand sides ofthe head without the necessity of making any adjustments after thedesired setting of the'blade is once obtained.

Another object of this invention is to provide a;

a razor blade container of unique construction including a sliding coverto allow easy access for insertion or removal of a razor blade.

A further object of the invention is to provide an index on theadjustable razor blade container whereby the adjustment of the cuttingedge of the blade may be readily and easily determined without resortingto guess work.

A still further object of the present invention is to so construct theappliance that the razor blade container can be inserted and removedthrough the back of the device, which is normally the top, for theplacement of a blade in or the removal thereof from said bladecontainer.

With the above and other objects in View this invention consists of thedetails of construction and combination of elements hereinafter setforth and then designated by the claims.

In order that those skilled in the art to which this inventionappertains may understand how to make and use the same I will describeits con struction in detail referring by numerals to the accompanyingdrawing forming a part hereof, in which:

Fig. l is a perspective view of a hair cutter constructed in accordancewith my invention.

Fig. 2 is an enlarged section on the line 2--2 cf Fig. 1.

Fig. 3 is a perspective view of the razor blade container removed fromthe hair cutter control 2 box or body and with the cover partiallywithdrawn.

Fig. 4 is a further enlarged fragmentary section of the control box,cover and latch.

In carrying out the invention as herein embodied 5 represents the hollowcontrol box or body open at the top and bottom and while the bottom isconstantly open the top is normally closed by a flat lid 6 resting onthe upper edges of the side and end walls of said body. The lidfunctions as the back of the device and is detachably held in place bysuitable means such as latches 1 pivoted on the exterior of said lid andengageable with the hook-like keepers 8 formed from the upper portionsof the side walls of the body, two of which are adjacent each end ofsaid body in opposed relation. The lid has notches 5, Fig. 4, to permitsaid lid to pass over the keepers which then project above the lid asufficient distance to allow the ends of the latches to pass under theinturned ends of said keepers.

On top of the lid ii is fixed a bridge 9 having a portion spaced fromthe outer face of said lid and between said spaced portion of the bridgeopposed lid face is a nut it screwed onto the threaded stem H, attachedto a razor blade holder or container !2, which stem projects throughaligned holes in the lid and bridge.

The razor blade holder or container I 2 includes a plate [3 having areverse flange Isl along its upper edge to form a track groove andinturne'd lugs 1 5 at the bottom adjacent the ends to constitute asegmental track groove. One edge of a safety razor blade I5 is insertedlaterally under the flange I4 into the groove and portions of said bladeslipped over the lugs and dropped into the segmental track groove.Finally a closure plate ii is slid endwise into the space between therazor blade and the flange M at the top of the holder and the lugs H5 atthe bottom of said holder to clamp the razor blade in place with cuttingedge exposed at the bottom of the holder.

The control box or body 5 has channel tracks M3 on the inside at theends thereof and said. tracks are perpendicular to the lid 6. Thesechannel tracks run from the top of the body to locations some distancebelow the bottom of said body in the form of extensions. The ends ofblade holder slidably fit in said channel tracks and may be moved up anddown by the proper manipulation of the nut ill.

Individual strand members it are formed from sections of. appropriatewire fashioned to substant ally triangular shape to constitute a guardnd the ends of the base portions thereof are fixed to opposite sides ofthe control box or body with acute angular portions 26 centered directlybelow the blade holder 42 so that when a latches 1.

blade is assembled in said holder and the latter adjusted the cuttingedge will be equally spaced from both of the inclined sides of theguard. The strand members 19 arebracedcbyreinforcing wires-l9.

A handle 2| is provided at one end of the body 5 whereby the device maybe used somewhat after the manner of a hair brush.

In order to assist the user of the hair cutter to adjust the blade forremoving theidesired amount of hair, the blade holder or container l2may have suitable indexmarks"22,"-such=as lines and associated numerals,thereoniior -cooperation with the lower edge of the control box orlbody'.5. ..These.index marks may.v be on any desirable portion of "the bladeholder andflfor illustrative purposes only, they are shown asbeingscribedqonlthellface of 'the'closureplate l1 atone end thereof.

To assemble a razor blade 'in the. hair; cutter or replace a. dullonewitha'new blade, the lid .01. cover his unfastened andthen removed from'the.body. or control" box. .Asllheflld' islbodily lifted-the blade'holder will .be movedupwardly in the channelv .tracks"l8(and finallywithdrawn therefrom. "With the blade holder. separated .from the bodyvor control boxthe closure plate another and the closureplate slippedintolposition. subsequentlyfthel blade holder,.with a razor bladetherein, is inserted inithe channel tracks i3 and propelledforwardlyuntil .the lid 6.,is seated at which time it. is secured. inplace .by the After. the ,p'arts'i have been. properly assembled thecutting'edge "of therazor blade may be adjusted relatively to. the.slantingsides of .the guard by turning. the nut it in the properdirection which will move 'saidblade Hi. towards or away from theangleZil. When the cutting edge of the blade is close to the angle 20longer portions of .hair. will bescut from a 'personshe'ad than whensaidic'utting .edgeis'Tur-ther' removed from said angle I23.

'In actual practice, after thewcu'tting edge of .the razor blade hasbeen properly. adjusted for cutting the hair to :the desired length.either slanting side of the guard is placed againstthe scalp and drawn'thereover causing the persons hair to enter the interstices of saidguard and the hair ends cut oil leaving the remaininghair of thepreselected length. After one side of the hair has been cut'the haircutter islshifted'. to the, oppositeside. of 'thepersons head. and theother slanting side of the guard :placed against the scalp and v.theoperations repeated without readjusting the cuttingy'edge of the blade.This insures that the hair on both sides of thehead will be uniformafter cutting.

It is to be particularlyinoted.that the adjustments of the razorbladeholder are accomplished from the. top of the control box or bodythereby eliminating the necessity .of having protruding partson'the'sides which might interfere with the proper contact ofthe, guard .withthe scalp. Attention .is..also called 'to the fact-that the same cuttingedge .ofthe razor blade can be utilized during one hair cuttingoperation without either reversing or inverting the haircutter foremployment on opposite sides of the head.

Of course I .do not wish to be limited to the exact details ofconstruction herein shown and described as these may be varied withinthescope of the appended claims without departing-from the spirit of myinvention.

Having described my invention what I claim as new and useful is:
